Lock 37 is one of the deepest fully manual stations on the Waterway. There are two walls designated on the upper side for mooring and a popular wing wall by the dam. Lock 37 has a quiet rural setting with ample grounds for boater camping.

Reconstruction of the Dam at Lock 37 - Bolsover

Parks Canada Investing in Dam Safety

The Dam at Lock 37 - Bolsover was built in 1902-1903 and was identified for reconstruction as part of the ongoing asset monitoring and recapitalization programme on the Trent-Severn Waterway.

Navigation will continue. However, this is a construction zone.

Public Safety is Important!

For your safety during the construction:
  • Remain in your boat at Lock 37. Staff will help you arrange visitor services and overnight mooring at another station.
  • When travelling downstream, use the floating dock above Lock 37 as the temporary holding area (blue line) to request passage.
The Government of Canada has made record investments to heritage canals. Our investments connect communities and ensure this infrastructure is available to those who need it.
